Which action should NOT be taken to control algae growth in pools?

Neglecting regular cleaning routines is a significant factor that can lead to uncontrolled algae growth in pools. Algae thrive in dirty environments where debris and organic matter accumulate, providing them with nutrients. Regular cleaning routines, which include skimming, brushing, and vacuuming, are essential for removing debris and preventing algae from establishing a growth environment.

The effective control of algae growth relies on maintaining a clean and balanced pool. Regular cleaning not only helps keep the water clear but also minimizes the chances for algae spores to settle and flourish. The other options focus on proactive or supportive measures that contribute to preventing algae growth, such as maintaining water circulation, which ensures that chemicals are evenly distributed and reduces stagnant areas where algae can grow. Shocking the pool regularly with chlorine is also crucial, as it eliminates existing algae and helps bolster the sanitizer levels to keep the water safe and clear. Using a pool cover during colder months can reduce sunlight exposure, limiting algae growth potential as well.
